The trigonometric ratios are;
- Sin A = 0.78
- Cos A = 0.625
- Tan A = 1.25
<h3>What are the trigonometric ratio?</h3>
The trigonometric ratios are sine, cosine and tangent. Now we have the hypotenuse of the triangle. Figure 1 has been shown in the image attached to this answer.
c = √8^2 + 10^2
c = 12.8
sin A = 10/12.8 = 0.78
Cos A = 8/12.8 = 0.625
Tan A = 10/8 = 1.25
